Abstract:The room-size test chamber developed for evaluating dichlorvos vaporizers adequately simulated the practical home conditions, since levels of air-borne dichlorvos concentration were found about the same both in the chamber and a house bedroom, each containing a typical dichlorvos vaporizer hung from the ceilings. Almost 100% kill of the susceptible laboratory house flies, Musca domestica L., occurred in about 70 minutes when they were exposed in cages to an air-hol'l1e dichlorvos concentration of 0.1 , µg per liter in the chamber, whereas when exposed as free-flying insects, comparable mortality occurred in 45 minutes. No adverse effect on plasma cholinesterase activity was observed in rats exposed in the chamber to a dichlorvos vapor concentration of 0.5 ,µg per liter for 3 weeks.
